The Artic 4000 charger (4A) is suitable for vehicles with 6V and 12V batteries, such as city cars, motorcycles, and jet skis. The Artic is a microprocessor-controlled, automatic charger that charges a battery monitoring-free at twice the speed of a traditional charger. The optimized charge maintenance allows the charger to remain connected to the battery during winter storage. It features an auto-restart function in case of a power outage, with all settings saved. The monitoring-free charging and maintenance maximize the battery's lifespan and performance. An LCD screen displays the charging process, including the battery status, charging mode, real-time battery voltage, and charging progress.
